Bounding the Capacity of Saturation Recording: The Lorentz Model and Applications

  title={Bounding the Capacity of Saturation Recording: The Lorentz Model and Applications},

This paper concerns the problem of bounding the information capacity of saturation recording. The bounds apply to a variety of systems such as magnetic tape recorders, magnetic disks, and optical data disks. The superposition channel with additive Gaussian noise is used as a model for recording. This model says that for a saturation input signal, x( t ) , (i.e., one that can assume only one of two levels) the output can be expressed as y(r) = f ( t ) + z ( t ) where f ( t ) is a filtered… CONTINUE READING
